I started when I was like 10, I think. Back then we had BASIC built into our computers and it came with a programming manual. We spent Saturday mornings and after school typing in games from magazines. Internet was unheard of. We had this thing called a "Library"... snow uphill both ways yadayada

I was 11 and saw Tron in a drive in, then Wargames and I was hooked.
First on any machine that was at any store (TRS-80, Coco, Atari's, TI-99's, Apple II), then mooching off my friend and his Vic 20 and Commodore 64.

Finally my parents gifted me with a 3.5Mhz Mattel Aquarius, and I'm still hacking at it via
an emulator running in Windows which I emulate with Crossover (ie not actually running Windows yeah!) on the Mac.

GW-BASIC when I was 5 years old, which was mainly used to toy around. C/C++ when I was 13, when I started 'real' coding. That was also the year my parents gave me a copy of Visual Studio 6.0 for my birthday - one of the greatest gifts I've ever received, to this day. Ironically, little things I learned with GW-BASIC continue to be useful on every level of computer science every day, so it was a better language to start with than I gave it credit for.

I spent many a happy day typing in their code (BBC Basic) on a BBC Micro, then later on an Acorn A3000. They provided code that would work with all the major BASICs of the day - GW-BASIC, Amiga, Acorn/Electron, Amstrad-CPC.

Those were the days! Since the mag was published in 1990, that would have made me 7 years old. Eek!

I started fiddling with BASIC on the Amstrad CPC when I was about 6 or 7, I think. I'd type in those program listings from magazines and fail to understand how they worked because I didn't know what a cosine was.
The day my dad gave a floppy disc to save my programs onto was a great day, even if I never got anything working. As a teenager I was more likely to spend time fiddling with level editors than writing actual code - I spent a long time trying to get the Quake engine to do things it wasn't really designed for (I never worked out how to write my own mods back then).
I learned C at uni when I was about 19, so I suppose I gradually got back into coding from then, and started writing games again about 4 or 5 years ago.
I think I remember "Let's Compute", but we were regular "Amstrad Action" readers in my house.
